Sept. 27, 1932. H. F. BHOGFORS TENS CARRYING MEANS Filed June 19, 1951 Even/072 a Mww Patented Sept. 27, 1932 UNITED STATES PATENT OFFICE TENS CARRYIN G MEANS Application filed June 19, 1931, Serial No. 545,531, and in Sweden June 27, 1930.

This invention relates to tens carrying means in cash-registers and has for its object to provide a reliable tens transferring mechanism in such registers.

With the above and other objects in View the present invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawing and m pointed out in the claim hereunto appended.

The invention is illustrated by way of example in the accompanying drawing, in which Figure 1 is a section at right angles to the totalizer shaft along the line II of Figure 2, Figure 2 shows the same portion, viewed from above. In both cases the totalizer is in totalizing position, and the totalizer wheel the tens carrying tooth of which is drawn 20 with a full line in Figure 1 shows the figure 9. Figure 3 shows the same section as Figure 1, but the release ratchet according to the invention is advanced to release position.

Figure 4 shows a detail of an already known method for carrying the released tens, and

Figure 5 shows a section of the frame.

Similar numerals refer to similar parts throughout the several views.

As is clear from Figures 1-3, the release ratchet 1 and the tens frame 2 consist of plates lyin along each other. The release ratchet 1 is held against the tens frame 2 by a bolt 3 which at the motion of the release ratchet slides in a slot 4-. of the tens frame, and the ratchet 1 is also held by an angularly bent lip 5 inserted into an opening 6 in the tens frame. In the lip 5 there is provided slot 7 which fits to the tens frame and prevents the ratchet 1 from loosening from the same. A spring 8 holds the lip 5 pressed against the upper edge of the opening 6. On the tens carrying tooth 10 on the totalizer wheel 9 there is an oblique surface 11 which upon turning of the totalizer wheel 9 in the direction of the arrow engages bolt 3 and pushes the latter to the left in the slot 4 until the lip 5 passes a sharp edge 12 in the opening 6. On being shifted to the left the lip 5 on account of the spring 8 is carried up into the catch 13 where it is held by the spring as shown in Fig. 3 until the totalizer moves to the right out of engagement with its actuating rack and the shaft 14 of said totalizer pushes against a cam 15 of the release ratchet 1, the latter being pressed down out of the catch 13 and being returned to the position shown in Fig. 1 by the spring 8. The totalizer rack bar 16 located to the left of the wheels as seen in Figs. 1 and 3 is provided with a catch 17 which the tens Q carrying ratchet 18 engages and prevents the bar from being pulled down by the spring 19 toward the upper edge of the slots 20 the length of which is equal to a tooth division. The ratchet 18 is provided with a lug 21 Which is engaged by the bolt 3 when the latter is shifted by cam 11 to initiate a carry. Ratchet 18 is thereby released from the catch 17 and the rack bar 16 is pulled down one tooth by the spring 19. When the totalizer is disengaged from the rack, said rack 16 is raised in a suitable way so that the ratchet 18 engages the catch 17 again.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is In totalizers where the shaft about which the totalizer wheels turn has a to-and-fro motion for engaging and disengaging the toothed wheels or racks turning the totalizer wheels, 2. release slide for tens carrying which when being advanced to release position is adapted to be carried to a fixed position by a spring, the release slide being ada ted to be carried back to the initial position y the totalizer shaft when the latter returns to a position out of engagement with the wheels or racks, such release slide being mounted in a frame so as to be slidden and turned, and being provided with a cam intended to cooperate with the totalizer shaft, and also with a lip positioned in an opening of the frame, said opening being provided with a catch into which the lip snaps when the slide is advanced to the release position.

In witness whereof I have hereunto signed my name.
